According to media reports, the new smelting technology, known as SmeltDirect, represents a major breakthrough for the ferroalloy industry, which can significantly reduce energy consumption and emissions in metal production. The technology, developed by South African mining company African Rainbow Minerals (ARM), is designed to reduce electricity consumption during ferroalloy smelting by up to 70 percent compared to conventional processes.
The traditional smelting of ferroalloys is one of the most energy-intensive stages in the mining and metallurgical chain, which makes energy costs a critical factor in the competitiveness of manufacturers.
Reduction of energy consumption and emissions
According to industry researchers, the SmeltDirect process can also reduce carbon emissions by about 60 percent, while reducing operating costs and increasing production efficiency.
In conventional smelting operations, about four MW of electricity may be required to produce one metric ton of alloy, while SmeltDirect reduces this requirement to about 1.2 MW per ton.
The technology also allows the use of small ores, slimes and low-grade raw materials, which are often difficult to process using traditional smelting technologies.
Potential for the revival of South Africa's ferroalloy sector
Analysts suggest that SmeltDirect could play an important role in reviving South Africa's ferroalloy industry, which has been struggling in recent years due to high demand.
